Template definition functions
int

DESCRIPTION
The libevtx_get_version() function is used to retrieve the library version.

RETURN VALUES
Most of the functions return NULL or -1 on error, dependent on the return type. For the actual return values see "libevtx.h".

ENVIRONMENT
None

FILES
None

NOTES
libevtx can be compiled with wide character support (wchar_t).

To compile libevtx with wide character support use: ./configure --enable-wide-character-type=yes or define: _UNICODE or UNICODE during compilation.

LIBEVTX_WIDE_CHARACTER_TYPE in libevtx/features.h can be used to determine if libevtx was compiled with wide character support.
